I've got one of these heading my way...as a coin nerd, I'm quite excited. I have one of the 25 BTC coins and it's my favorite coin to carry around. Very cleverly designed binary inscription on the reverse too!

I'd call that a piggy bank since you have to smash it to get the money out.

Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable. I never believe them. If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins. I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion. Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice. Don't keep coins online. Use paper wallets instead.

I got my silver bitcoin today...I couldn't resist opening it up and playing with it. Might have to order another one to keep all nice and shiny looking. Does anybody know if the silver bitcoin has a different message encoded in binary on the back than the 25 BTC coin?

A few other points:These are proof struck. Very deep field. Slightly thicker and smaller diameter than an American Eagle 1 oz silver coin. Reeded edge It's not a copy of the 25 BTC coin scaled down. The binary inscription is different.

The binary message is indeed different. One of the coins says "You asked for change, we gave you coins" and the other says "Bitcoin - an idea too big to fail".

I just barely got in a new batch of hologram stickers today. Part of my sticker batch is new silver-foil stickers (instead of gold-colored-foil) for the 10 BTC coin, intending to use silver stickers on the non-plated coins and gold-colored stickers on the gold-plated coins, despite already having issued lots of unplated coins with gold stickers (it's all I had).

If I order a second silver round, can I get one with a silver hologram to go with my gold one...or do you have a bunch of prestickered silver/gold combos you need to move first? Are you going to use silver stickers on the 5btc coins?

I do indeed have silver stickers on the 5 BTC coins, but I have a large number of them already made up with the gold stickers, and they sell slowly. I will honor requests for sticker type in the notes.

I might need to do some R&D on the silver stickers for the silver coin - they arrived slightly larger and won't fit without a small trim, which is a pain. I might get them done over or might just not use them.
